Monostotic Paget's disease of the second metacarpal.

Paget's disease of the bone is a focal chronic disorder proceeding with elevated osteoblastic and osteoclastic activity in the affected area. The most common sites are pelvis, femur, lower lumbar vertebrae and skull. Monostotic disease is reported in 15-30% of all cases. We report a case of monostotic Paget's disease of the second metacarpal, which is a rare location even for polyostotic disease.
